In a survey of 5100 randomly selected T.V. viewers, 40% said they watch network news programs. Find the margin of error for this

horsena [70]

Answer:

Margin of error = 0.01344

Step-by-step explanation:

Margin of error = critical value × standard deviation.

critical value for 95% confidence interval = 1.96

Standard deviation = √[(p)(q)/n]

p = 0.4, q = 1 - p = 1 - 0.4 = 0.6, n = 5100

Standard deviation = √[(0.6×0.4)/5100] = 0.00686

Margin of error = 1.96 × 0.00686 = 0.0134

What is the approximate volume of a cone with a height of 8 cm and a radius of 12 cm? Use 3.14 for pie.

lawyer [7]

Answer:

Step-by-step explanation:

The volume of the cone is found using the volume formula for a cone $V=\frac{1}{3}\pi r^2h$ .

Substitute h=8 and r = 12.

$V = \frac{1}{3}\pi r^2h\\V = \frac{1}{3}\pi (12^2)(8)\\V=\frac{1}{3}\pi *144*8\\V = \frac{1152}{3}\pi \\V= 384\pi \\V=1,205.76$

So the volume is approximately 1,206 cubic cm.
